Glossary & Optimization Guide

CPA (Cost Per Action)

The fixed amount a network pays you for a successful conversion or lead. Maintaining a positive spread between your ad spend and this payout is the core of affiliate media buying.

ROI vs. ROAS

ROI (Return on Investment) considers all expenses including fees, showing true profit percentages. ROAS (Return on Ad Spend) only measures revenue generated directly from ad dollars, often overstating actual profitability.

Optimization Strategy

To maximize margin, aim to lower your CPC (Cost Per Click) through A/B testing creatives, while simultaneously increasing your landing page conversion rate. Even a 1% increase in conversion rate can double net margins.
